Research


My current research is focused on Computer Vision and Robotics, Image Retrieval, Image Processing and Analysis, Machine Intelligent and Pattern Recognition.

Compact Composite DescriptorsThe family of compact composite descriptors includes descriptors for 3 types of images. A group of 2 descriptors combines color and texture information in order to describe natural color images. In this page you can read more details about CCDs and download the related libraries. Read more… MPEG-7 Visual DescriptorsFrom this page you can download an open source implementation (in C#) of the Scalable Color Descriptor, Color Layout Descriptor, Dominant Colors Descriptor, as well as the Edge Histogram Descriptor. Read more… GRIRE: This project is a collection of tools for implementing the BOVW model. So apart from the image analysis tools, it also offers methods from the field of Information Retrieval (weighting models etc) adjusted to meet the Image Retrieval perspective.. Read more…
noptilus Image Retrieval Tools: In this page you can find details regarding several open source and freeware applications/libraries for Content Based Image Retrieval. Read more… img(Rummager): img(Rummager) brings into effect a number of new as well as state of the art descriptors. The application can execute an image search based on a query image, either from XML-based index files, or directly from a folder containing image files, extracting the comparison features in real time. In addition the img(Rummager) application can execute a hybrid search of images from the application server, combining keyword information and visual similarity. Read more…
MMRetrieval Search Engine: In this web application, we present an experimental multimodal search engine, which allows multimedia and multi-language queries, and makes use of the total available information in a multimodal collection. All modalities are indexed and searched separately, and results can be fused with different methods depending on a) the noise and completeness characteristics of the modalities in a collection b) whether the user is in a need of high initial precision or high recall…Read more… sfly Simple Descriptors: We employ the SURF detector to define salient image patches of blob-like textures and use the  MPEG-7 Scalable Color (SC), Color Layout (CL), Edge Histogram (EH) and the Color and Edge Directivity Descriptor (CEDD) descriptors to produce the final local features’ vectors named SIMPLE-SC, SIMPLE-CL, SIMPLE-EH and SIMPLE-CEDD or “LoCATE” respectively. Read more…
